Depends.
On your property, using your voice? Sure.
At 2:30am, you yelling it 20ft from your neighbor’s house? Probably nor, mainly as it disturbs other people’s normal use of their home.
On someone else’s property? Depends on if they allow it.
In public, in the commons? Sure, as long as people are allowed to ignore you.
For a training set. Natural, and familiar conversations.
